Scope of application

EYW1 (DW45) Intelligent Universal Circuit Breaker (hereinafter referred to as Circuit breaker) and is mainly used in distribution networks with an AC frequency of 50Hz , rated operational voltage ≤690V and rated current 400A-6300A. It is used to distribute electrical energy and protect lines and equipment from being damaged by overload, under voltage, short circuit, single-phase grounding and other failures. Having art-oriented appearance,

high breaking capacity, zero arcover and a variety of intellectualized protection functions, the circuit breaker can be used for selective protection with accurate action, no unnecessary power cut, and better power supply reliability.

Circuit breaker has standard RS485 communication interface with telemetering, remote control, remote regulating and remote signaling functions which be able to meet Cluster Control Center and Automatic system's Request.

Circuit breaker without intelligent release and sensor can be used as disconnector.

This product meets the standards GB 14048.2 and IEC 60947-2.
